Yesterday I opened the driver's door of my car, prepared to get out, and stopped just in time: lying on the floor, just where I would have put my foot, was a banana skin.

Come on. Nobody really leaves banana skins lying on the floor if they're not in Tom and Jerry cartoons, do they? And leaving it just where someone would put their foot is just suspicious. I'm sure that if I'd slipped on it, some unlikely chain of events would have ensued which culminated in an anvil dropping from the ceiling of the car park.
